The Lifeline of Substations Is BatteriesSubstation Battery Sizing CalculationImportant Battery NotesSubstation Battery Sizing Calculation Wrap UpNow, let''s do some math and size a flooded cell, lead-acid battery for a substation. The battery will be rated 125V DC nominal and have an amp-hour capacity rated for an 8-hour rate of discharge. In most substations, the 8-hour rate of discharge is the standard. It gives operators a solid 8-hour window to sort out any AC power supply issues beforeSee more on engineercalcs electricalacademia
